She detained Bob to take him to Iron Man for a failed attempt to contain him. At least the writer of this was aware of that story, Cates seemed to be not only totally unaware about it but also unaware about the more recent Annihilation Scourge event.
For that matter, since this new mini is acknowledging mystic continuity regarding both Doc Strange and Clea operating currently, and because Sentry was the final villain of the last Strange series (which treated Bob with at least some dignity), I wondered from the first issue preview if the disaster scene page was just a random person with Sentry powers causing a Nitro style accident, or if it maybe was the site of the villain headquarter that was blown up by Sentry at the conclusion of that Strange series. I'm not sure even a nuclear explosion of souls could really get rid of Sentry's body when it was intended to be a powerful vessel even in death. Maybe this is a sequel of sorts.
